EUGENE — Madison Boer protected the No. 21 Oregon baseball team's one-run lead late, and Eddie Rodriguez launched his team-leading seventh home run of the season as the Ducks ended the 2010 regular season with a 6-5 victory over California on Sunday at PK Park.

The Ducks (38-22, 13-14) finish tied for fifth in the league standings with Cal (29-23, 13-14).

Oregon will learn its postseason fate today, when the 2010 NCAA Division I Baseball Championship 64-team field with first-round regional pairings will be revealed in a live, half-hour telecast on ESPN at 9:30 a.m. Pacific.

Oregon trailed 5-2 heading into the bottom of the fifth, but Rodriguez erased that deficit with one swing of the bat. J.J. Altobelli's two-out single through the left side got the rally started and Jack Marder's two-out double to left put runners on second and third for Rodriguez.

In his last game at PK Park, Rodriguez drove Chris Petrini's first pitch of the at-bat over the wall in left center to tie the game at 5-5.

Oregon then took the lead in the bottom of the sixth after Danny Pulfer singled off Cal reliever Erik Johnson. Pulfer moved to second on a sacrifice bunt and advanced to third on a wild pitch before Steven Packard's pinch-hit RBI single put the Ducks ahead 6-5 for their first lead of the series.

Zack Thornton (9-0) was credited with the win for Oregon after tossing six innings on the mound, allowing five runs on five hits while striking out five. Thornton remained undefeated on the season and his nine wins tie an Oregon single-season record.

ARIZONA 3, OREGON STATE 1 — At Corvallis, Steve Selsky's sixth-inning home run proved to be the game winner as Oregon State concluded its regular season with a loss at Goss Stadium.

The Beavers, however, took the series from the Wildcats by virtue of victories Friday and Saturday. Oregon State will now await postseason word.

Selsky's home run was a two-run shot in the sixth that broke a 1-1 deadlock. It came off OSU reliever Tyler Waldron, who ended the weekend with 61/3 innings of work against Arizona, where he allowed just two hits and two runs with 10 strikeouts.

Both hits and runs, however, came Sunday and sent Waldron to 4-5 this season.

Arizona (33-22, 12-15) opened the game with a run-scoring single in the first off the bat by Jett Bandy that gave the Wildcats an early 1-0 lead. The Beavers then scored their only run of the game in the third when Tyler Smith came in on a passed ball.

Smith, Adalberto Santos and Andrew Susac each had two hits for the Beavers, who totaled eight on the afternoon. Susac extended his hit streak to five games with his 2-for-4 day.

The Beavers finished the regular season with a 31-22 overall record and 12-15 mark in the Pac-10.
